Rochester to New York

What the Data Says About ROC to LGA

The Rochester to New York corridor (ROC → LGA) covers roughly 254 miles and is served by 4 carriers, based on Bureau of Transportation Statistics reporting. Across 4,016 flights in the dataset, this route posts a 85.6% on-time rate with an average delay of 87.6 minutes when flights run late. Over the most recent 24 months of BTS data, 2,146 flights were recorded on this pairing — 71 cancelled (3.3%) and 4 diverted (0.2%). Those baseline metrics tell you what to expect before you book.

Having 4 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 4,016 total flights analyzed, the 85.6% on-time figure is statistically meaningful rather than a small-sample fluke. The 87.6-minute average delay applies only to flights that actually ran late, so it is not the average wait across all departures — the majority of flights on this route depart on time under the BTS definition of a delay (15+ minutes past schedule).

Looking at recent months, May 2023 posted the best performance on this corridor at 98% on-time, while Jan 2023 came in at 75% on-time — a 24-point gap between best and worst recent month. For travelers evaluating the ROC to LGA route, the combination of a 85.6% on-time rate, 87.6-minute average delay, 3.3% recent cancellation rate, and 4 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
